The present invention is directed toward an apparatus comprising a high speed rotating disk or bowl for nanofiber spinning from the rotational sheared thin film fibrillation at the enclosed serrations with the optimized stretching zone to produce the defects-free nanofibrous web and nanofibrous membrane comprising a nanofiber network with a number average nanofiber diameter less than 500 nm that yield the crystallinity higher than the polymer resin used in making the web.

Polymeric nanofibers and nanofibrous web

Apparatus for production of polymeric nanofibers

A method for laying down a nanoweb of nanofibers from a centrifugal spinning process by a combination of an air flow field and a charging arrangement. Fibrous streams in the form of fibrils of molten polymer or polymer solution are discharged from a rotating member into an air flow field that is essentially parallel to the direction of discharge of fibrils at the point of discharge of the fibrils. The fibrous streams are attentuated and directed by means of the air flow field onto the surface of a collector to form a nanoweb. The fibrous streams are charged along all or at least a portion of their route from the point of discharge to the surface of the collector.

There is provided a portable substrate carrier enclosure. The carrier enclosure has a carrier support; a displaceable cover; spacers between the support and cover; a gas inlet; and a removable lid. There is also provided an assembly and a process for depositing an air-sensitive material onto a substrate using the portable substrate carrier enclosure.
